Application filed April 21, 1910. Serial No. 556,'736.

Be it` known that l, JOHN a citizen of the United States of America, residing at Braddock, in

the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvefor Operating De- Reciprocatin Movements, of

ence being had therein to the accompanying ravving.

My invention relates to attachments for operating devices by reciprocating movements, and relates more particularly to devices of this character adapted to be connected up to utilize the exhaust from a motor such as a steam, gas or internal combustion engine, the attachment being particularly adapted to operate cleaning or polishing devices for motor vehicles.

The objects of my invention are to provide a device which will be .reciprocated by the action of the exhaust impulses coperating with means tending to place the mechanisln in position where a succeedingr impulse may provide a reciprocating movement', the impulses actuating the mechanism in one direction; to provide a mechanism will be 'operative regardless of the number of impulses per unit of time; to provide a device which ,is simple and etlicient in operation, durable in construction, and which can be manufacturedat a relatively low cost.

With the above and such other objects in View asmay hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts to be hereinafter specitically described and then claimed.

Reference Will now be had to the drawings forming part of this specification,

thereof can be varied or changed, as to the' yation of a cleaning With my invent-ion,

wherein there are illustrated the preferred embodiments of the invention, but it is to e understood that the'structural elements size, shape and manner of assemblage wit-hout departing from the spirit of the invention.

head adapted to form part of the device', F ig. t5 is a longitudinal sectional view taken centrally of Fig. 5, Fig. 7 is a plan of a cleaning or polishing strap forming part of the device.

In the accompanying drawings the refer-- ence numeral 1 denotes an engine having cylinders 2 provided with an exhaust pipe 3 having a valve 4 of the tivo-way type and a conventional form of muiiler 5.

Connected to the valve 1 by a pipe 6 is a of provided with a nipple 8. The nipple 8 extends into the funnel shaped end 9 of a section of hose 10, the funnel shaped end 9 being connected to the nipple 8 bya spider 11. The end of the hose section 10 is detachably connected to the cap 12 of a cylinder 13, the opposite end of said cylinder being closed by a head 14! having a transverse slot or elongated opening 15 formed therein.

cup-shaped piston 16 and detachably connected to said piston, as at 1,7 is a piston rod 18 adapted to entend through the. slot 15 of the cylinder head 14. Encircling the piston rod 18 between the head 14 and the piston 16 is a coiled expanding Ispring 19, the object'of which will presently appear.

Detachably mounted upon the outer end of the piston rod 18 is a head 20 and connected to said head is a heart-sl'lapedl flexible metallic plate 21 covered by a piece of fabric 22, as l plate 2l and fabric 22 constituting a polishing and cleaning head.

In lieu of the a. strap can be used, comprising a piece of fabric 23 having one end thereof provided with a link 24A, and attached to the opposite end is a piece of flexible rubbei1 25. Vlrlhe link 2li is provided with a head 2G, whereby it can be connected to the end ofthe piston rod 18.

The valve 4f is normally open whereby the exhaust 'from the cylinders 2 can pass through the mutller 5, and when it is desired to use the polishing device,wthe section of hose 7 is attached Vto the pipe 6 and the valve 4fclosed, wherebytheexhaust will be d'etiectcd Ainto-the lsection of hose 7. rAs

Movablv mounted in the cylinder 13 is a felt or flannel, the head 20,

cleaning and I'iolishing head hose or flexible pipe 7 having the end therethe exhaust passes through the nipple 8 into the section of hose 10, the cu -shaped piston 16 Will be moved forwardiv, placing the spring 19 under compression,.consequently the heart-shaped polishing head Will. be moved forwardly and after the exhaust has Spent itself, the spring 19 will restore the polishing head and piston 16 to their normal position with the exhausted air passing out through the funnel shaped'end 9 of the seetion of hose 10. As will be-readily understood, the successive impulses of th'e exhaust will gradually till up that portion of the attachment beyond the end 9, after which the succeeding impulses will he delivered upon the cushion so formed and will quickly exhaust out through the annular space surrounding the nipple 8, such impulses acting on the piston 1G through the cushion pro- 20 'vided by the exhaust gases located in the section 10. ,As will be readily understood, the spring 19 tends to return the piston4 to initial position, the time requiredto do this being dependent upon the spring itself, and necessarily being substantially the same at 'all times. Consequently, when the pressure of the impulse causes thel piston to move forwardly to compress the spring, the spring will, if a sutlicient amount of time' is given, return the piston to its initial position; when this action takes place, the length ot' reciprocation of the cleaning element, is at its `maximuml I By r'easoinlion'ever, of the fact that the spring presents a time element requiring a fixed period, such maximum movement would necessitate the runningof the motor at an exceedingly low speed, without *materially 'increasing the polishing effect. This relatively slow movement, while possi- 40 ble .with 'a motor having' 'the exhaust impulses of considerable time intervals is not a favorable result when an attempt is made to place the attachment on a motor having a plurality ot.' cylinders delivering the exhaust to a common outlet, a construction in which the explosions are so rapid as to prevent the provision ot' a sufficient length of time for the piston to return to its normal g position. This-fact is taken care of in the present instance, by the facility to operate the attzurlnnentuwith equal and in reality st n'icrior results, by automatically shortening the stroke of reciprocation of the piston and increasingr the number of strokes per unit of time, this action being obtained by reason of the t'act that the time of sucessive impulses is shorter than that required for the spring to return the piston to its normal position, with the result that the succeeding impulse becomes etl'eetive on the piston before it has returned to its normal position. Obviously, the greater the increase in impulses per unit of time, the shorter will be the stroke of the piston, cach impulse., how- 65 ever, providing for the stroke. In this manner, the motor can be run at high speed,

and the vibrating movement of the cleaning attachment be had at a corresponding high speed with short strokes, enabling the attachment to more rapidly produce the cleaning effect as well as the polishing effect. vAt the same time, the high speed developed does not provide excessive vibration to the attachment itself (the cylinder), since the direction of movement of the piston corresponds to the direction of vibration or reciprocation of the cleaning attachment, so that all movements are substantially in a single plane. s

then the cleaning or polishing Istrap isA to be used, the cylinder 13 can be held in one hand and the-end of the strap held by the other hand, thereby permitting of con-l siderable pressure being brought )to bear upon the material to be cleaned or'polished, while -the flexible strap will 'conformto the contour of the material. The flexible rubber" Q5 being held in the hand and the cylinderin operation, the piece of polishing'fabric can be easily moved back andforth, thereby 90 permittingof both hands being held stational-y. lt is in this connecti. n that I do not care to confine myself to the material used either in connectionwith the polishing head or the polishing strap. y .c 9 lt is apparent from the foregoing that4 my polishing device can be 'made part -of an automobile equipment. and with the auto' mobile stationary and the engine in operation. tbe mo'st intricate parts. f the auto-4 mobile can' be thoroughly cleansed. i i
